THREAD-CUTTING TEMPLE FOR LOOIVIS- SPECIFICATION forming part of LettersPatent No. 765,687, dated July 26, 1904.

Application filed March 30, 1904.

To all whom it may concern:

Be it known that I, EDWARD S. STIMISON, a citizen of the United States, residing at Hope'- dale, in thecounty of Worcester and State of Massachusetts, have invented an Improvement in Thread-Cutting Temples for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates more particularly to the type of loom-temple forming the subjectmatter of United States Patent No. 585,465, dated June 29, 1897, wherein the temple-head is provided with means to cut the filling end extending from the'selvage of the cloth to the automatic filling replenishing mechanism after such mechanism has been operated to supply the shuttle with fresh filling. In the temple shown in said patent the temple-head is slotted transversely at its outer end toreceive cooperating fixed and movable blades which are arranged to engage and cut the filling end, the pivot for the outer end of the temple-roll extending across the slot. The movable blade is notched at its under edge to clear the pivot and permit the rocking and sliding movement of the blade when operated. In practice it-sometimes happens that owing to wear or looseness of the parts the blade will in its movement engage the pivot, and both it and the blade are damaged, so that the blade may be broken or the pivot cutthrough.

One of the objects of my present invention is the improvement in the construction of the temple described in the patent referred to whereby injury to the roll-pivot or the movable blade, as hereinbefore set forth, is made impossible.

Another object of my invention is the production of a more extended bearing for the movable blade, whereby its movement is steadied and wear reduced.

Ihave also provided means herein to prevent any twisting or distortion of the temple-head out of its proper operative position.

These and other novel features of my invention will be fully described in the follow- Serial No. 200,684. (No model.)

ing specification and particularly pointed out in the appended claims.

Figure 1 is an outer end elevation of a thread-cutting temple and its stand of the type hereinbefore referred to and having one form of my present invention embodied therein. Fig. 2 is a top or plan view thereof. Fig. 3 is a longitudinal sectional detail through the temple-head on the line 3 3, Fig. 2, the roll and its pivots being shown in elevation. Fig. 4 is a transverse sectional detail taken through the blade-receiving slot on the line 4 4, Fig. 3, just after the movable blade has been rocked and is about to be retracted; and Fig. 5 is a cross-section of the slide-bar or shank on which the temple-head is mounted, taken on the line 5 5, Fig. 1.

The temple-stand A, adapted to be secured to the breast-beam of the loom, the templehead comprising the pod B, cap B, the heel B attached to the pod, and the toothed roll B between the pod and cap and turning on pivots carried by the cap, may be and are in their general construction substantially as in Patent No. 585,465, referred to. The inner pivotal supportl for the roll B is of usual construction.

At its outer end the cap is longitudinally extended at 2, and a transverse slot 3 is formed therein, the inner wall 4 of the slot having a threaded hole to receive a roll-pivot 5 screwed thereinto, the hole being countersunk to receive the head of the pivot, as shown in Fig. 3. It will be seen that said pivot is sustained wholly by the wall 4 and its head lies flush with the face of said wall, a hole 6 being made in the outer wall 7 of the slot opposite the pivot and large enough to admit the blade of a screw-driver or similar tool, by which the pivot is inserted and removed.

An upright steel cutting-blade a is secured to the pod and projects upward into the slot midway between its side. walls, substantially as in the patent aforesaid.

The slide-bar or shank B, to be hereinafte referred to, has a lateral enlargement 6 adjacent the extension 2 of the cap and slotted in continuation of the slot 3, and the movable cutting-blade C is inserted in the slots, the outer end of the blade being longitudinally bifurcated to present two separated sides 0 0 each downturned to form a hook 0 the fixed blade a passing up between the two sides 0 0 this construction being practically the same as in Patent No. 585A65.

The wire spring d, spirally coiled at d to fit over a stud d on the bar B, has oneend (1 bearing against a shoulder 8 on the bar, the opposite end of the spring being dow'nturned and bent into a loop d fitted over a lateral lug 9 on the heel 10 of the blade 0, the springnormally acting to project the outer end of said blade through the slot 3 in elevated position, as shown in Fig. 1.

At its inner end the blade is laterally enlarged to form stop-lugs 11, which limit its spring-induced movement, and a shoe 12 on the blade slides on the beveled underside 13 of ear 6 (see Fig. 1) to permit the shoe to slide and rock when the blade C is operated, substantially as in the patent referred to.

Aelug l4-on the upper edge of the blade acts as a stop to prevent withdrawal of :the blade accidentally, the lug bringingup against the spring-coil d if the retractive movement of the blade should for any reason he improperly prolonged.

In order to remove the blade C, the spring must first be removed and then the blade can 2e slipped and withdrawn from the temple- By mounting the roll-pivot 5 as herein-described and leaving a perfectly-clear path for the movement of the blade C, I not only obviate absolutely any chance of damage to either of said parts, but I am enabled to very materially increase the bearing-surface for the sliding movement of the blade.

Referring more particularly to Fig. 4:, it will be'seen that this flat bearing-surface 15 extends from the shoe 12 substantially to the bifurcated end of the blade, such surface riding upon the bottom of the slot 3 and by its extent decreasing wear and also steadying the movement of the blade. In order to prevent the temple head from twisting out of its proper relation with regard to the cloth, I have made the slide-bar B L-shaped in crosssection and comprising a main upright web 16 and a lateral flange 17 at its lower edge, the flange connecting with the shelf 18, forming a part of the pod, the heel B of the temple being made integral with said shelf.

As shown in Fig. 5, the stand A is recessed appropriately to receive the L-shaped bar B, the web and flange construction thereof not only preventing any twisting or distortion of the temple-head, but greatly strengthening the bar itself without undue increase in weight.

In the operation of the temple the movable blade normally stands with its hooked end elevated and'projecting beyond the face of the temple-head, as shownin Figs. 1 and 2.

As the lay heats up it first strikes the heel 10 of the blade C and immediately rocks the blade, depressing the hooked end into the position shown in Fig. 4, and as the lay completes its movement the blade is drawn into the temple-head, and if there is a filling end between the selvage and filling -replenishing mechanism such filling end will be caught by the hooked end of the movable blade and drawn across the edgeof the fixed blade a, the filling end being severed at that point. This operation is the same as in the patented temple previously referred to, as will be manifest from an inspection thereof.

In the present embodiment of my invention the stand A will be provided with the usual spring (not shown) to push the templehead toward the back of the loom, the lay when beating up forcing the temple-head toward the breast-beam, as is common in reciprocating temples.

Thenovel features of my present invention, however, are not restricted to this particular form of temple, as the same may be employed with equal facility on temples of different construction;

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. A temple-head provided with a toothed roll and having a transverse slot at its outer end, a roll-pivot sustained by the inner wall of the slot, cooperating fixed and movable cutter-blades located in the slot, andmeansto operate said movable blade, the path of movement of the latter being wholly beyond the outer end of said roll-pivot.

2. A temple-head provided with a toothed roll and having a transverse slot at its outer end, a roll-pivot sustained by the inner wall of the slot, the outer wall having an opening opposite the pivot to permit its insertion or removal, an upright fixed blade within the slot, a cooperating movable blade therein, and means to operate said movable blade, the path of movement of the latter being wholly beyond the outer end of the roll-pivot.

3. A temple-head comprising a pod and a cap, a roll carried by the cap, the latter havinga transverse slot in its outer end, a rollpivot sustained by the inner wall of the slot, a fixed blade and a cooperating movable blade. both located in the slot beyond the outer end of the roll-pivot, and means to operate the movable blade.

1. A temple-head having a transverse slot at itsouter end, a fixed and acooperating movable blade located within the slot, a spring to project the movable blade, and a stop on the latter to prevent its removal from the slot while the spring is in position.
